Man Leading a Ram by the Horn

Bronze is an alloy of copper and tin that has been used for thousands of years to make objects as diverse as sculpture and figurines, weapons and armor, and jewelry and tableware. The addition of tin and sometimes lead made the alloy more versatile and lowered its melting point; another common copper alloy is brass (copper and zinc), which was in widespread use in the Roman period. Although other materials, like stone, glass, and terracotta, were available, copper alloy items were valued for their golden sheen, versatility, and durability. The material lent prestige and beauty to objects like these statuettes, most of which would have been dedicated to the gods. Modern bronzes are often artificially patinated, like the Rodin sculpture in this colonnade. While ancient bronzes were sometimes gilded or deliberately darkened, the unaltered surfaces naturally acquired a red, green, or brown patina over time.
